The invention provides a preparation method of bent glass containing printing ink patterns. The method comprises the following steps: printing; carrying out film hot-bending, namely performing hot bending on a plain film obtained in the previous step in a film hot-bending mold, wherein the die assembly temperature during hot bending is 60-85 DEG C, and the plain film is hot-bent and molded into abent film; designing the size of the film hot-bending mold, so that the bending degree of the obtained bent film is higher than the bending degree of the bent glass so as to reserve resilience marginfor the bent film; and laminating, thereby obtaining the bent glass containing printing ink patterns. According to the method disclosed by the invention, the printing ink patterns are printed on the film material, and the problems of bubbles, fold, indentation, fracturing and the like in the preparation process of the bent glass containing printing ink patterns are solved under conditions of independently molded film, the set resilience margin of the film, the selected specific film base material thickness, specific film hot-bending die assembly temperature and the like. The bent glass prepared by the method disclosed by the invention is high in precision of the printing ink patterns on the surface and attractive in product appearance.
